SEEING-HEEL.

Specification of Letters Patent.

Patented Apr. 19, 1910.

Application filed June 17, 1909. Serial No. 502,825.

To all whom it 'may concern:

Be it known that I, ERNEST A. C. Soiioor, a citizen of the UnitedStates, residing at New York, in the county of New York and State of NewYork, have invented certain new and useful Improvements in Spring-Heels, of which the following is a speeifieation, reference being hadtherein to the accompanying drawing.

My invention relates especially to the construction of the heels ofboots and shoes, andhas for its object the provision of an effectivevand durable spring heel adapted to eliminate the jar which takes placewhen heels-'fofgordinary construction are employed.

To'fattain the desired end, my invention consists in certain novel andusefull combinations and arrangements of parts, and peculiarities ofconstruction and operation, all of which will be hereinafter irst fullydescribed, and then pointed out in the claims.

In the drawing, Figure lis a side elevation of a heel embodying myinvention showing the same in place upon a shoe. Fig. 2 is a top plan.view of the heel removed from the shoe. Fig. 3 is a vertical,cross-sectional view of my improved heel detached. Fig.

4f is a plan view of the heel with the top plate removed. Fig. 5 is aplan view of the top plate of the heel, looking from below.

Similar numerals of reference, wherever they occur, indicatecorresponding parts in all the figures.

1 is a metallic top-plate having holes 2 therein for'the reception ofscrews, or the equivalent, forv fastening t-he heel to the sole of aboot or shoe.. The depending rim or.- edge of the plate l is providedwith a groove; 3, as particularly shown in Figs. 3 and 5 of the drawingand with screw-threaded perforations 4 for the reception of screws 5,the inner ends whereof are not threaded, and project inward somedistance beyond the material of plate l.

6 is a metallic plate having a depending rim 7 and a groove 8 in itsupper face corresponding to the grooveB in the inner side of theplate 1. Extending upward from the plate 6 is an annular projection 9having slots 10 therein opposite to the screws 5 and into which thesmooth ends of said screws project.

11 is a ring of rubber, or equivalent, conforming to the shape of thegrooves 3 and 8, and arranged to fit snugly therein, as

illustrated in Figs. 1 and 3 of the drawing.

12 is a spiral spring, located between the plates 1 and 6.

13 is a heel piece of leather, or any other preferred material, fittingsnugly into the rim of the plate 6, and secured against displacement bya screw 14e, or the equivalent.

l5 is a leather heel piece, nailed or otherwise securedy to the piece 13and which may be readily removed and replaced when When constructed andarranged in accord ance with the foregoing description my improved'spring heel will be found very effective in use. The spring 12 may beof such rcsistance'a's to conform to the weight of the wearer, and beinginterchangeable, there is no ditiiculty in substituting one spring foranother. The rubber ring `11 not only supplements the action of themetallic spring, but serves as a packing to exclude moisture from theinterior of the heel, and permits the heel to conform to the slope ofthe surface being walked upon. The screws 5, working in the slots 10ac'- curately guide the parts while being compressed and expanded, aswell as holding the upper and lower plates together.

Having now fully described my invention, what I claim as new therein,and desire to secure by Letters Patent, is:

1. A spring heel comprising a pair of f plates having telescopingprojections, said plates being provided with annular grooves, and anelastic ring arranged in said grooves.

2. A spring heel comprising a pair of plates having telescopingprojections, said plates being provided with annular grooves,

means for limiting the movement of said plates in respect toeach other,and an elastic ring arranged in said grooves.

3. A spring heel comprising a pair of plates having telescopingprojections, said platesbeing provided with annular grooves, an elasticring arranged in said grooves, a spring arranged between said plates,and means for limiting the movement of said plates in respect to eachother.

4. A spring heel comprising a plate adapted to be secured to a shoehaving a depending rim provided with .an annular groove at its edge, asecond plate provided with an annular groove at its edge, and having anannular projection extending upwardly therefrom between the rim of thefirst mentioned plate, a spring arranged between said plate and anelastic ring arranged in said grooves.

5. A spring heel comprising a plate adapted to be secured to a shoe,said plate being provided with a depending rim having an annular grooveat its edge, a second plate provided with an annular groove at its edge,and having an annular projection telescoping up into the rim `of therstmentioned plate, a spring arranged between said plate, and an elasticring arranged in said grooves, and means for limiting the movement ofsaid plates in vrespect to each other.

6. A heel for shoes comprising a pair of plates having .telescopingprojections and corresponding grooves in their opposing faces, a ring ofrubber arranged in said groove, one of said plates being provided with adepending rim, and a sectional leather heel secured within said rim.

7 A heel for shoes comprising a top plate and a bottom plate havingtelescoping pro-l jections, said plate being provided with correspondinggrooves in their opposing faces, a ring of rubber arranged in saidgroove, a coiled spring arranged between are adapted to pass forsecuring the same to a shoe, said plate being provided vwith a dependingannular rim at its edge having an annular groove, a second plateprovided with an annular projection extending up between the rim of theirst mentioned plate, and having slots, said second mentioned platehaving an annular groove registering with the groove'of the rstmentioned plate, an elastic ring arranged in said grooves, screwsextending through the rim of the rst mentioned plate into the slot ofthe projection of the second mentioned plate, a spring arranged betweensaid plates, and a leather heel carried by the bottom plate.

In testimony whereof Ihereto aiiX my signature in presence of twowitnesses.

ERNEST A. C. SCHOOF.
